SPRING-WHEEL FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 586,026, dated July 6, 1897.

Application filed December 1, 1896.. Serial No. 614,088. (No model.)

.To CLZZ whom it may concern:

Be it known that I, ELLIS D. GREENE, a citizen ot the United States, residing at Barry, in the county of Pike and State of Illinois, have invented a new and useful Improvement in Spring Vehicle-Wheels, which improvement is fullyset forth in the following specification and accompanying drawings, in which- Figure 1 is a central section of a hollowcylindrical hub, showing my improved springs and their adjuncts; Fig. 2, a detail view of the sections of the spindle-boxing; Fig. 3, a detail showing the manner of attaching the inner ends of the coiled springs to the spindleboxing; Figs. at and 5, sectional end views showing the position of the coiled springs before and after being subjected to pressure.

My invention pertains to certain i1nprovements in vehicle-springs; and my purpose is to provide a novel, efficient, and durable device specially adapted to bicycle-wheels and designed to obviate the several disadvantages attending the use of the costly, unreliable, and short-lived pneumatic tires and other appliances, which, being attached to the peripheries of wheels, are necessarily exposed to fatal injuries in addition'to inevitable wear and tear.

The essential feature of my invention consists of a hollow cylindrical hub provided interiorly with a pair of adjustable coiled springs, the inner and outer ends of which are attached, respectively, to the axle-boxing and the interior wall of the hub.

The peculiar construction and exceptional advantages of the device will be apparent by referring to the accompanying drawings, in which A designates the spindle, the outer ends of which are attached to the steeringfork 2 in the usual manner. The spindle-boxingis composed of a main section 3, having a reduced rounded extension 3, adapted to engage the central aperture in the smaller section of' the spindle-boxing, which is thus independently revoluble, for the purpose here- The hub is composed of a hollow cylinder ends fitted into grooves 6 in the end plates 7 and made secure by transverse bolts 8.

ing reverselycoiled have their outer ends secured at diametrically opposite points Within the shell of the hub, as at 11. It will be-understood that if desired twoor more pairs of springs may be employed. In order to adjust the tension of the springs and adapt them to carry more or less weight, a spider-wheel 12 is fitted to the outer end of the smaller section of the spindle-boxing and provided with a set-screw 13, which passes through the said section and engages the extension 3 oi the main section. If the set-screw be withdrawn until it releases the extension, the smaller section may be turned independently by means of the radiating arms of the spiderwheel. The tension of the springs may thus be increased or relaxed to the desired degree and secured by resetting the screw. It will be observed that the springs being reversely arranged, as described, any tension exerted on one will be communicated directly to and equalized by the other.

In order to obviate the reeling of the hub on the spindle, a duplicate spider-wheel 14 is attached to the main section.

The radiating arms of both wheels engage the annular ridges 15, projecting outwardly from the sides of the end plates of the hub.

A sprocket-pinion 16 is mounted on. the outer end of the main section of the spindle: boxing, and the wheel-spokes 17 are suitably attached to the borders of the end plates 7.

hat I claim as new is- In a spring for bicycles and other vehicles, the herein described cylindrical hub, the spindle-boxing composed of a main section and an independently-revoluble supplemental section, the reversely-coiled adjustable sprin having their inner and outer ends attached respectively to the spindle-boxing and I the encircling rim of the hub, and means for adjusting and regulating the tension of the springs, substantiallyas and for the purposes specified.

In testimony that I claim the foregoing I have hereunto set my hand, this 13th day of November, 1896, in the presence of witnesses.

ELLIS D. GREENE.
